Boleite was first found out in Boleo, Mexico in 1891, inside of a location on the Baja peninsula that is becoming renowned for unusual minerals. Boleite is these kinds of an abnormal and complex mineral which the definition of its chemical composition and crystal framework have undergone several revisions since its to start with discovery.
The 1st specimens of boleite ended up identified by Eduoard Cumenge, a French mining engineer. Another scarce halide mineral with the identical location, with an analogous construction and a slightly unique chemical composition, was named cumengite in honor of Cumenge.
There are various attributes of boleite which make it of specific desire to collectors. For something, it has an strange chemical composition, getting a hydrated guide copper silver chloride hydroxide. It has considerable portions of those metals, with about forty nine% direct, 14% copper and nine% silver. Secondly, it's a fascinating crystal framework, given that boleite is always pseudocubically twinned. That is definitely, Each and every Δαχτυλίδια cube-like crystal of boleite is in fact made up of 3 rectangular box-like crystals oriented at right angles to one another. Boleite also has a Δαχτυλίδια Γυναικεία really beautiful indigo colour plus some really scarce transparent crystals are actually Lower as gemstones.

Like Δαχτυλιδια bulgari other halide minerals, such as fluorite, boleite is kind of gentle, by using a Mohs hardness rating of only 3 to three.5. It's a vitreous to pearly luster. It is an unusually dense mineral, with a ΧÏυσά Δαχτυλίδια particular gravity of five.05. Only a few minerals, for instance hematite and cassiterite, have a higher density. Boleite's refractive index can be very substantial at two.03-2.05; better than sapphire, sphene and demantoid garnet.
Along with cumengite, There are a variety of other minerals associated with boleite, like pseudoboleite, chloroxiphite, paralaurionite, matlockite, chlorargyrite, bideauxite, atacamite, mendipite and diaboleite.
In addition to the deposit in Baja, Mexico, boleite is located in Broken Hill in New South Wales, Australia; inside the Mammoth District of Arizona in The usa; and in the Mendip Δαχτυλιδια swarovski Hills of Somerset, England.
